SNAP-0N SUCKER-ROD GUIDE.

Application filed May 1,

This invention'relates to snap-on sucker rod guides.

The general object of the invention is to provide a sucker rod guidewhich can be economically manufactured and quickly installed.

A specific object of the invention is to provide a flexible member forsnapping on a sucker rod to act as a guide therefor.

Anotherobjectof theinvention is to provide a sucker rod uide comprisinga piece of metal or other exible material which is arranged in spiralform and is alsoadapted A further object of the invention is to providea spirally wound sucker .rod guide having means thereon for engaging thesucker rod.

Other objects of the invention will be apparent from the followingdescription taken in connection with the accompanying drawings wherein:

Fig. 1 is a central sectional-view showing a portion of a well with apump casing therein having a sucker rod equipped with my invention.

Fig. 2 is a view similar to Fig. 1 on a larger scale.

Fig. 3 is a section on line 3-3 of Fig. 2.

' Fig. 4 is an elevation showin the manner in Cyvhich the guide isarranged a out a sucker r0 Fig. 5.115 a sectional view of the modifiedform of my invention, and

Fig. 6 is a sectional view showing a further modification of myinvention.

Referrin to the drawing by reference characters have shown a well casingat 10. Within this well casing I show a pump casing at 11. A. sucker rodis shown at 12.

The sucker rod guides embodying the features of my invention is shown at14. This guide is preferably flexible and may be made of metal or othermaterial. My guide is constructed to normally take the position of aspiral, and the upper and lower ends of the spiral if desired may bebentabruptly inwardly as at 15. with the extreme ends 16 pitched toward thecenter of the spiral so that the edge 17 may bite into the rod 12 toprevent up and down movement of the rod between the rod andguide.

The guide being spirally arranged does not prevent the flow of fluidthrough the pump casing, but does effectively support the sucker rod.The guide will also provide an 1926. Serial N0. 105,996.

outer edge which as .the rod moves up and down in the well prevents theaccumulation of parafline or other solids on the inner wall of thecasing. The guide will be of material which is of suflicient softness tocause no injury to the inside of the casing 11 due to the rubbingcont-act. The guide may be provided'with perforations 18 which may bedistributed at intervals as desired.

The inner diameter of theguide is preferably slightly less than theouter diameter of the sucker rod so that the resilient properties oftheguide will maintain it in proper position. The guide will be sprung asshown in Fig. 4 when installing it.

In Fig. 5 the guideis shown as rovided with supports 20 for rollers 21,w ich are adapted to engage the inner wall of the easing 11. Theserollers may be used'whenever desired. Y

In Fig. 6 I show a modification of my invention wherein the flexiblesucker rod'guide 25 comprises a flexible stri of material such ascompressed fibre or ot er substances in which a flexible strip'26 ofmetal or other material is imbedded. The flexible strip 26 serves tomaintain the shape of the" guide while the softer material 25 preventswear but does not prevent the flow of fluid through the casing 1 Fromthe foregoing description it will be apparent that Ihave provided aneconomical and effective sucker rod guide which can be quicklyinstalled. My invention also serves as a casing or tubin protector sinceit properly centers the suc er rod so that the latter remains out ofcontact with the inner wall of the casing or tubin Having thus descriEedmy invention what I claim is: g 1. In combination with a well casing, a.sucker rod movable in said casing and means engaging said casing andsaid sucker rod to prevent flexing of said rod, said means comprising astrip of material arranged to entirely surround and to engage said rodthroughout substantially its entire length.

2. In combination with a well casing having a sucker rod movabletherein, a member arranged on said sucker rod and engage Mid 3. Incombination. with a sucker rod, aguide comprising a strip of materialshaped to surround and engage the sucker rod throughout. its entirelength, said guide forming a curved channel in conjunction with the rod.

4. In combination with a. sucker rod, a flexible guide comprising astrip of material bent to spiral form and having portions thereofgripping said sucker rod, the extremity of said strip having an edgebent substantially parallel to the rod to engage the rod.

5. A. sucker rod guide comprising a stri of material bent to form aspiral, the ones of said spiral being bent abruptly inwardly and havingthe extreme end pitched at a slight angle to the spiral whereby a sharpedge is provided for engaging a sucker rod.

6. A sucker rod guide comprising a strip of material arranged in curvedform and having a central aperture adapted to receive a sucker rod, saidspiral having a normal signature.

nsaaeee central diameter slightly less than the diameter of the suckerrod which it is ada ted to engage, whereby there will be tight iit'iotional engagement between the guide and rod.

7.111 combination with a well easing a sucker rod movable in said casingand guide means engaging said casing and said sucker rod, said guidemeans engaging the periphery of the rod and having a spirally arrangedwall therein.

8. In combination with a well casing having a sucker rod movabletherein, a member arranged on said sucker rod and engaging said casing.said member comprising a strip of fiat flexible material rectangular incross section. said strip being bent so that one narrow edge of thestrip engages said casing while the other narrow edge engages said rodto hold the strip in position.

I In testimony whereof, I hereunto atfix my RALPH a. nosrio.
